Man is 90% microbes

Man is 90% microbes. The intestines alone contain almost 2 kg of bacteria.

The human body, it turns out, is almost entirely composed of microorganisms. However, you should not be afraid before the time, he writes: these creatures are not alien life forms. For trillions of microscopic life forms, the human body is home.

“We are, in fact, only 10% human, and everything else is germs, ” says Dr. Roy D. Slitor of the Irish Institute of Cork. After four years of thorough study of the subject, he came to the conclusion that the true role of bacterial populations living in the human body is undeservedly diminished.

Our relationship with single-celled creatures turned out to be so close that progressive scientists now consider humans and the bacteria that inhabit it as a single superorganism. “Today bacteria are considered as a virtual organ, the waste products of which are significantly higher than that of the liver, ” explains Dr. Slitor.

According to him, the human body contains about 500 different types of bacteria. Thanks to their incessant reproduction, about 100 trillion single-celled creatures live in the adult human body - almost ten times more than the few trillion cells that make up the human body itself. For example, the intestines alone contain almost 2 kg of bacteria.

According to Dr. Slitor, bacteria are not only our companions, but also irreplaceable helpers. “This bacterial-human interaction is mostly symbiotic, ” says the scientist. "This means that in exchange for food, bacteria are involved in digestion, vitamin production and strengthening our immune system." In addition, friendly microorganisms protect the host from pathogens of infectious diseases by fighting "hostile" bacteria.

For lovers of yoghurts and other "live" fermented milk products, this news is certainly good. However, Dr. Slitor warns that the strengthening properties of "probiotic" foods are very short-lived. “Most of these bacteria do not stay in our body.

They pass through the body, failing to organize a colony, ”he says sadly. On the other hand, the constant consumption of these types of foods can help strengthen the colonies of beneficial bacteria. This is especially true when the body is weakened by taking antibiotics.
